The mechanism for locking the crank 19 consists of a depending pawl ordog 27, pivoted at its upper end to the frame 5. the crank engagingmember 27 of which is normally disposed in the path of travel of theouter end of'the crank 19 in such manner as to prevent further movementof the latter when it reaches this point, as later described. Thedog 27is normally retained in its crank engagin a spring actuated bell-cranklever 28, which is pivoted at 29 to a 'fixed member on the frame .5, andhas a projection 28' on its lower end which bears against the hack-of anextended portion of the dog 27. A spring 30, is wound around a stud. on.the lever 28 and bears between a rigid pin and to exert an inwardpressure on the lower end of the lever 28. v

The device for releasing the dog 27 from engagement with the crank 19,comprises a link 31, one'end of which is provided with a slot into whicha pin 32 on the dog 27 ex tends, and the other end of which engages acurved releasing bar 33 which is located between the segment 4 and theactuator bar 13 in contact with the upper face of the downwardlyextending portion 8 on each 'ofthe'type-bar actuating-arms 7. The bar 3is here shown as extending downward at each end and pivoted at 34 at apoint against the key lever A, but any other man- .er of mounting thebar by which it can ciilatory movei sired.

In operating the typewriter mechanism just described, a button A isdepressed, thereby rocking the key-lever A on its pivotal mountings 2 soas to move the operating arm 3 upward through the guide slot in thestationary segment 4. This brings the upper end of the operating arm'3into contact with the downwardly inclined end 8 of the arm 7, thusmoving the latter upward on its pivotal mounting 7' so as to dispose thehook 12 in actuating-bar 13, as shown in Fig; 2. As the inclined portion8 of the arm 7 moves upward, the .bar 33 is moved backward by reason ofthe inclined portion 8 bearing against the bar at a point 45 from itscenter, thus acting as a wedge to move the bar 33 backward on itspivotal mountings 34. The rearward "movement of the int. may be employedif debar 33 carries the slotted link 31 rearward therewith, so as tothrow the projection 27 on the lower end of the dog 27 out of engagementwith the crank 19, which permits the latter to rotate on the shaft 20and thus position, by means of ave a certain transverse reciprocal orosrelease the bar 13, The bar 13 is then caused to move forward by meansof the tension of the springs 16 bearing against the links 14, the link18 pulling upon the loose crank 19 to carry the pawl 21 over the camsurface 23, the cam 23 travel free from engagement with the ratchet 22while the bar 13 is moving in a forward direction. The springs 16 act onthe link 14 to impel the actuating bar 1.3 forward with considerablevelocity the forward movement of the bar 13 acting to impel the type bar10 upward against the platen roll through the arm '7 which has beenpreviously disposed in front of the movable bar 13, as before described.A uniforn'i impact of all the type in the machine on the platen roll isin sured for the reason that one spring or set of springs 16 control theforward movement of the actuator-bar 13, which bar operates on all thetype bars. The moment the impression is made by the type bar 10, thespring 9 returns it and the arm 7 to the normal position shown in Fig.1-. In the meantime. the pawl 21 has been carried clear of the cam 23 bymeans of the link 18 and crank 19, which are carried forward by theactuating bar 13. The moment the pawl 21 is released from thccnm 23 aspring 2}, on

the pawl throws it into engagement with the rotating ratchet wheel onthe shaft 20, S0 that as the ratchet revolves the crank 19 will becarried therewith, thus pulling upon the link 18 to return the bar 13back to its normal position, in opposition to the spring 16 where it isretained by the dog 27, reen gaging the crank 19. The moment the crank19 is engaged by the dog 27, the heel of the pawl 21 strikes the cam 23which action rocks the pawl 21 and releases it from engagement with theratchet 22, in which released position it is retained by the cam 23until the crank i9 is again released from the dog 27 and is again movedforward by the springs 16, be ore described. The moment the bar 13starts hack to its rear ward position it releases tlN' llook 12 on thearm -7 thereby allowing the spring 9 to pull the arm 7 downward untilthe lower end of the inclined portion 8 comes in contact with. theslotted segment 4, the lower end 8 of the arm 7 moving rearward intocontact with the edge of the actuating arm 3 extending through thesegment 4, so as to move the latter rearward against the tension of thespring 6, as shown in dotted lines in Fig. 2, the spring 9 at the sametime restoring the type bar 10 to normal. As this occurs, the spring 6returns the arm 3 and key lever A to normal, the upper end of the arm 3pass ing beneath the lower end of the wedge-end 8 in position .foranother operation, and the releasing bar assuming its former positionover the inclined portion 8 of the arm 7. The platen roll 35 is mountedon a carriage llu ill

36, which is adapted to travel back and 'forth on a trackway 37, asiscommon. in typewriter construction. As the operation of the platenroller and the carriage 36 forms no part of the present invention, themechanism for operating the same is not here shown,
